>But I've been told that humans are incapable of digesting gluten
Ayyyy lmao boi you just got popscienced.
"Digestiveness" of molecules is determined by the enzymes the consumer has.
We have enzymes enough to break off all sorts of proteins, so I'd be amazed if we wouldn't be able to digest gluten.
Even if we couldn't, it would either be digested by our gut flora or just pass out like what happens with most our food.
Heck, most people don't even realize it but we are unable to digest plant matter, it's all cellulose.
What we do is we pulp it, drench it in acid, knead it and then pass it along 12m of intestines in the hopes that we get some nutrients out of the plant cells we just Saw-ed (a very small portion of it gets digested by our gut flora though).
So everytime you're eating a salad you're just getting some of the minerals, vitamins, lots of the water content and that's it.
If we could actually digest plant matter a crop of lettuce would almost be like bread in terms of carbohydrates.
